The invention discloses a tension and compression loading rate variable test system and method. The system comprises a creep maintaining mechanism, a loading regulation and control mechanism, a loading mechanism and a data acquisition and analysis system, the creep maintaining mechanism is used for applying constant loading force to the sample through the loading mechanism under the action of the loading regulation and control mechanism, the loading mechanism comprises a base, a second piston type oil cylinder, a lower chuck, an upper chuck, a second fixed cross beam and a second movable cross beam, and the lower chuck, the upper chuck, the second fixed cross beam and the second movable cross beam are sequentially arranged from bottom to top; the two clamping heads are used for clamping the two ends of the sample to stretch the sample, and the space between the second fixing cross beam and the upper clamping head is used for pressurizing the sample; an oil pump in the loading regulation and control mechanism
